To @ZZ whom it may concern:

Beit known that we/FHEODOR KOMMERELL and EDWIN EDWARDS, both of Munich, Bavaria, Germany, have invented certain new and useful Improvementsin Automatic Flushing Apparatus for Canals, Tater-Closets. and Similar Objects, of which the followiugis a specification.

Patents for this invention have been granted in Germany, No. 37,115. dated March 10, 1886; in England, No. 6,519, dated May 14, 1886, and in France, No. 175,845, dated April 80, 1886, and a patent has been applied for in Austria-Hungary on November 11, 1886.

This invention relates to an automatic flushing apparatus for canals, water-closets, and similar objects, which operates automatically and periodically, consuming a small quantity of water, which quantity can be adjusted to varying` requirements, forming an effective flushing apparatus for canals, closets, urinals, and the like, or the apparatus can be employed as an automatic and adjustable deviceforemptying reservoirs, vessels, and for similar uses.

Our improved apparatus will operate more effectively than any intermittently acting flushing apparatus now employed, as it operates accurately with the very slightest (even drop by drop) supply of water, so that with a consumption of, for instance, one hundred liters in twenty-four hours, at intervals of one, two7 or more hours, according` to the size of the reservoirs, while at the same time, as is the case with all known non-automatic tiushing` devices, water can be taken out ofthe res- In the intermittently-operating fiushingapparatus known up to this time the entire and automatic emptying of the reservoir-that is, the obj ect for which the apparatus is 1n ade is always dependent on the quantity of the water-suppl y. As has been proved even with apparatus ofthe newest construction, the same require a water-supply of at least two cubic meters in twenty-four hours if they are to operate accurately, and as this quantity of water can only be very exceptionally used for ilushing closets, urinals, and the like, it renders their general introduction in most cases imrllhe general adoption of our improved apparatus will be highly desirable in sanitary respects, for the reason that none but an appara` tus with a very small consumption of water will render it possible to effect a regular daily .or repeated automatic iiushing` of the closets when apartments stand empty-forinstance, during the vacations, or at any other time when the closets are left unused for any length of time-thusprcventi ng the trap from becoming dry and preventing the penetration of sewer or foul gases to the rooms. lin order, however, to attain this object, which is of such eminent sanitary importance, at a slight cost, an apparatus had to be constructed which would effect and deliver a powerful automatic flush with a small consumption of water, and this object, it is believed, is attained by the present apparatus.

To clearly explain the nature of the invention reference is made to the accompanying drawings, in which- Figure 1 represents a vertical section, and Fig. 2 a top view or plan, of the improved apparatus.

The apparatus consists of Aa water tank or reservoir, A, provided with a trough-shaped reversing oroseillating lever c, which is so,

constructed that a metallic ball or rolling weight, b, can roll to and fro with the least possible friction. rIhe fulcrum c of this lever a is arranged on the reservoir or tank, and the lever at one end is connected to a tloat,f, and the loose connecting-rod g ofthe liushingwalve l1, by means of the joints or hinges d c.

The metallic or other ball b, on the one hand, and the correspondingly heavy iiushing or outlet valve h, represent the two powers operating on thelevcr,whilethe doat, iu conjunction with the valve stem or rod, sets these powers in action at suitable times. 'ihelength of the connecting-rod g is in proportion to the height of the water to be stored in the tank, said rod being provided at its lower end with a disk, which moves freely in the hollow space of the valve, rising by the action of the float when the water rises in the tank until it comes nearly into contact with the cap t' of the valve. At the same time the float willvpress the shorter arm of the lever gradually upward, and at the IOO moment when the latter is brought beyond the horizontal line the ball will roll to the opposite end of the lever, and thus lift the float, and also the valve, sufficiently to allow the water to flow off at It without any obstruction.

If the water-line is so low that the fioat is not in contact with it, the weight of the float, in conjunction with that of the connecting rod and valve,will overcome the weight of the bal1,draw the shorter arm of the lever a down, and allow the ball to roll back to its original position, thus iirmly closing the valve.

In order that the outlet-valve be correctly guided when it is raised or lowered,three guiderods, Z, are provided. These are bent over at their upper ends, so that the valve when raised will strike against them and be prevented from leaving them. y

Should the quantity of water thus let off not be sufficient or a second flushing be considered desirable, the reservoir can be provided with a reserve chamber or space, C, and a siphon, D, in which case, as represented in the accompanying drawings, the inflowing water is led into the said chamber and the partitionwall p arranged to be somewhat lower than the overflow height of the Siphon. The water flows out of this reserve-chamber into the main chamber and sets the emptying mechanism in operation, the water flowing off through the valve and main pipe B, and sucking the air out of the pipe leading to the reserve-chamber,thus

v producing a partial Vacuum in the same, so

that the siphon is put into action. This cornbination with the siphon is, however, not an absolutely necessary feature of the invention, as by suitably constructing our improved apparatus any quantity of water can be brought to iiow over automatically.

In cases where a flush is desired before the iioat can set the parts in operation automatically, it is only necessary to pull a cord or chain attached to the long arm ofthe trough-shaped lever a, as shown in dotted lines at q, when the valve will be opened, and will close again as soon as the cord, chain, or its equivalentis released, so that a flushing of the closet or other apparatus can be effected Vat any time, even after the automatic iush, for the reason that when the automatic flush operates the tank is never emptied even when auxiliary compartments with a Siphon are employed, as the siphon will only empty the auxiliary or reserve chamber. The intervals between the automatic iiushings or emptyings of the tank or reservoir are regulated by adjusting a cock, m, in the water-service.

If from any cause the automatic flushing device should not act,the water entering the tank would flow off through the siphon. It is evident that the various parts can be modified without departing from the tenor of our invention.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim isl. A periodical flushing apparatus consisting of a tank, an outlet-valve, a shifting weight, connections between said weight and valve whereby the shifting of the former shall unseat the latter, a iioat, and connections between said float and weight, whereby the rising of the float shall shift the weight, in subslantially the manner specified.

2. A periodical flushing apparatus consisting of a tank, an outlet-valve. a tilting lever, a shifting weight applied to said lever and movable to either side of the fulcrum thereof, a float connected to said lever, and a loose connection between the lever and valve, whereby the lever may be moved by the rising of the float 'far enough to shift the weight before the valve will be unseated, substantially as set forth.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
